Though Khloé Kardashian has been seen with baseball player Matt Kemp over the past three weeks, the two are not dating, according to a report Monday.

People magazine said the reality-TV star, 29, was spotted with Los Angeles Dodgers outfielder Kemp at a Beverly Hills gym Friday morning, just hours before filing for divorce from former NBA player Lamar Odom.

Helping spur rumors was a photo Kemp, also 29, posted on Instagram the same day showing what People said was the Kardashian family's Christmas tree. "Best time of the year!!" he wrote. "It's gonna b a Cali Christmas this year."

Kemp and Kardashian, whom People said are longtime friends, attended a Drake concert together at Los Angles' Staples Center on Nov. 25, saw John Legend perform at L.A.'s Nokia Theatre on Dec. 1, and attended Jay Z's show at the Staples Center on Dec. 9.
